LGTM

## Three browsers by Halloween

[Firefox Nightly](http://nightly.mozilla.org/) now includes `srcset` and 
`x`-descriptor support behind a flag – instructions on how to enable 
and test the feature are [here](http://codepen.io/RICG/pen/poKfj). The 
feature should be on-by-default 
[shortly](https://bugzilla.mozilla.org/show_bug.cgi?id=1018389) and 
`sizes`, `w` descriptors, and `picture` support are [right around the 
corner](https://bugzilla.mozilla.org/show_bug.cgi?id=picture). Nothing 
is certian, but if things keep progressing apace, full `picture` spec 
support should be shipping on-by-default in FireFox 33 on October 14th.

Over on the Blink side of things, `srcset` and `sizes` received [the 
three magical 
“LGTM”s](https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/GRfwz951FHo
) they needed to come out from behind their experimental feature flag 
and should be on-by-default in M38 — shipping in Chrome 38 stable on 
September 26th and Opera 25 around the same time.


## Webkit’s not *too* far behind

Yoav has successfully wrangled the existing WebKit `srcset` 
implementation into shape, [aligning it with the 
spec](https://bugs.webkit.org/show_bug.cgi?id=133504) and setting the 
stage for [`sizes` 
support](https://bugs.webkit.org/show_bug.cgi?id=133620).

[Rumor has 
it](https://twitter.com/helloanselm/status/473719818756317184) that iOS 
8 even supports `x` descriptors in `srcset`. Baby steps!


## In the meantime, Picturefill...

PictureFill 2.1, which brings `srcset` parsing in-line with the spec, 
hit 
[beta](https://github.com/scottjehl/picturefill/releases/tag/2.1.0-beta).

If you haven’t given Picturefill a go yet, you really should code like 
it’s 2015 and give it a whirl. If you *are* using it, [let them 
know](https://github.com/scottjehl/picturefill/issues/258)!

## And hey! Weren’t those 
[t-shirts](https://dribbble.com/shots/1471972-Responsive-Images-Community-Group-IndieGogo-Campaign) 
great?

I got mine in the mail last week and I just want to say that they’re 
really terrific. Thanks again to [Geri Coady](http://www.hellogeri.com/) 
for the design, [United 
Pixelworkers](http://www.unitedpixelworkers.com/) for the printing, and 
RICG chair [Mat Marquis](https://twitter.com/wilto) for running 
logistics. And thanks most of all to all of you for buying them and 
[making Yoav’s tireless implementation work 
possible](https://www.indiegogo.com/projects/picture-element-implementation-in-blink)!

We’ve been getting a lot of questions about how to buy the shirts now 
that the campaign is over. We don’t have anything firm to report yet 
but we’re looking into our re-print options. If you missed the boat on 
these, keep an eye out!


See you in a couple of weeks!
